then tee the dump valve into the drivers side port which looks to be for a boost gauge
correct, just been looking into my old builds and the one way valve goes between the inlet and map sensor, and the dump valve (is what could be causing the problem) so either t-piece it into the other vac that goes to your boost gauge ect or remove the dump valve altogether and block the hose up with a dump valve bung.....
it will chatter like a bitch too
